据新华社北京1月5日电(记者胡喆)1月5日,我国研制的发射重量最重、技术含量最高的高轨卫星——实践二十号卫星成功定点。该卫星是由中国航天科技集团有限公司五院抓总研制的东方红五号卫星公用平台首飞试验星,将对我国自主研发的新一代大型地球同步轨道卫星平台——东方红五号卫星公用平台进行全面在轨验证。

BEIJING, Jan.5(Xinhua)-- China's highest-orbit satellite with the heaviest launch weight and the highest technical content -- the practice 20-- was successfully targeted. The satellite is the first test star of the Dongfanghong 5 satellite public platform developed by the fifth hospital of China Aerospace Science and Technology Group Co., Ltd., which will carry out a comprehensive in-orbit verification of the new generation of large-scale geostationary orbit satellite platform, the Dongfanghong 5 satellite public platform, which has been independently developed in China.

  目前卫星已完成转移轨道变轨工作,对东五平台的主要关键技术进行了验证,东五平台首飞取得成功,后续将继续开展在轨试验与验证工作。

At present, the satellite has completed the shift of orbit, the main key technology of the East Fifth Platform has been verified, the first flight of the East Fifth Platform has been successful, and the subsequent in-orbit test and verification work will continue.

  实践二十号卫星成功定点标志着东方红五号平台验证取得重大突破,意味着我国正跻身国际一流通信卫星“俱乐部”。航天五院总工程师、东五平台总指挥周志成院士介绍,和我国现役“主力产品”东三、东四平台相比,东五平台重量、功率、在轨寿命等关键性能指标又有了跨越式提升,将填补我国大型卫星平台型谱的空白,可满足未来20年大容量卫星应用需求。

The successful target point of satellite 20 indicates that Dongfanghong 5 platform has made a great breakthrough, which means that our country is becoming one of the world-class communication satellite \"club \". The chief engineer of the Fifth Academy of Aerospace and academician Zhou Zhicheng, commander-in-chief of the East Fifth Platform, introduced that compared with the \"main products\" and the East Fourth Platform in active service in China, the weight, power and track life of the East Fifth Platform have been improved by leaps and bounds, which will fill the gap of the large-scale satellite platform spectrum in China and meet the demand of large-capacity satellite application in the next 20 years.
